IMPROVED VAIIVE FOR SUGAR-FANS.

I tip firlgtbnlt Infant in in flgtst ittttcrs amt amt mating and of ittime.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, LEWIS COLWE LL, ofthe city and county and. Stateof-New York, have invented a. certain new and improved Valve forSugar-Pans; and do hereby declare the following to be s t full, clear,and exact description of the same, refcrence being had to theannexeddrawing making part of this specification, in which I Figure 1 shows averticalsection through the centre of said valve, and

Figure 2 is a view of said valve turned bottom side up.

The object of this invention is to facilitate and more perfectly controlthe escape oi" the sugar from the pan. This object I accomplishby-makingmy valve-chest globular in form, and forming upon one sidethereof a. nozzle, fitted with a poppet-valve. upon a stem runningthrough the centre of said chest, and which stem is also fitted with abreaker upon its upper end, to break the crust which sometimes forms inthe nozzle of'the valve-chest or neck of the pan, and which, whenthe oldstyle of valve or cock is used, prevents theflow of the, sugartherefrom. r I

To enable those skilled in the-arts to whichmy invention appertainstomake and use the same, I will proceed to describe the constructionand-operation thereof. V v

Similarletters of reference represent corresponding parts of thedifferent figures in the annexed drawing. The valve-chest is shown inthe drawing byvi a, the valve by b,.the valve-stem by d, the breaker byc, the valve-stemguideby e, and the lever for workingtlie valve by f.- INow, let this chest be bolted to the neck'of 'the p an by the flangev,-so as to make a joint impervious to the sugar or air, and let it bedesired to draw out the sugar from the pan. I i

The operator takes hold of the leverf, and, by a single impulse of hishand, opens the valve wide, and at the same time breaks-any incrustations that may have formed in the neck of the pan or nozzle 'to the valve,

and leaves the sugar free to issue on all sides ofthe valve, throwing itagainst the curved wall of'the chest, which-is contracted at its lowerend or mouth, so as to throw the sugar towards thecentre from all sides,thus drawing it in a concentrated stream into the receiver;

In practice, the-valve b ismnde of Indiasrubber, and the valve-seat isridged up, so as to clear itself'of sugar, and insure a ti'ghtjointunder the valve, and the leverf is made longer than shown in thedrawing, and is secured by any known mechanical means to hold the valvetightly against its seat.

One end of the valve-stem guide e is fitted into a mortise made in thechest of the valve, and the other is held by a screw, in a. flange'caston the chest, which screw may be readily taken out,and by whichthe"valve-,

stem and'breaker can be taken out of the chest, leaving the opening ofthe pan entirely unobstructed.

. Having now described the object, nature, and practice ofmy inven tion,I claim, and desireto secure 'by Letters Patent-'- Y 1. In combinationwith a sugar-pan, a valve, enclosed in aglobular chest,arranged so as toconcentrate the sugar into 1 solid stream as it issnes from the chestand pan into the receiver.

2. The use of a. poppet-valve enclosedin a chest, in combination with asugar-pan, substantiallyas described. 3. The use of the'breaker c on theend of the valve-stem, to break the crust of. the sugar, and clear tlieneck of the pan or nozzle of the valve-chest, and allow a free exit forthe sugar, substantially as described.

4. Armin in the valve-stem uide 0 in the chest, substantial] asdesoriberh b which it, the valve-stem g a z: y .Y

and breaker, can beremoved out of" the chest, by simply taking out thescrewin the endof said valvest em' guide.
